[Prior Art] Conventionally, a person who has carried a person or an article in a box-shaped container and transported between the floor of the building in the longitudinal direction has been generally used. As shown in Fig. 8, the elevator is connected to the tank 3 1 (lifting cabinet) and the counterweight 3 2 (balance hammer) of the passenger or the article by the elevator rope 3 3 made of steel cable, and the elevator rope 3 is 3 Winding on the pulley 35 of the winding machine 3 4 (motor) at the top of the lifting path, and making it a bucket type operation. However, if the casing 3 1 or the counterweight 3 2 can be made lighter, the cost of the entire elevator can be reduced, and the burden on the building can be reduced. However, when the weight of the casing 31 or the counterweight 3 2 is lightened, the friction between the pulley 35 and the elevator rope 3 3 is reduced due to the weight reduction, and the power driven by the winding machine cannot be driven. The problem is effectively transmitted to the elevator ropes 3 3, resulting in poor control and inability to safely drive the passenger or article box 31. In other words, it is quite difficult to reduce the weight of the elevator. [Problem to be Solved by the Invention] Therefore, the present invention provides a product related to a lift that can be expected to have a high hope for the weight of the elevator -6-(2) 1270523. [Means for Solving the Problem] The belt for driving the elevator according to the present invention is characterized in that the belt for driving the elevator is driven by the frictional force of the elevator rope connecting the lifting body and the counterweight, and is controlled. The creep caused by the shear deformation during the operation of the elevator slides the rubber hardness to about 50 to 90 degrees. ® The belt for the elevator drive is driven by the friction between the cabinet connecting the elevator and the elevator rope of the counterweight, so that even the weight reduction caused by the weight of the cabinet or the counterweight is the cause. The frictional force of the elevator rope is reduced, and the frictional force of the elevator rope is affected by the belt for driving the elevator, so that the driving force of the elevator can be ensured, because the creep sliding caused by the shear deformation during the operation of the elevator is controlled. The rubber hardness is set so that the stability during operation can be ensured. Also ® The above operation refers to the state being driven or being stopped. Furthermore, since the rubber hardness of the belt is set to about 50 to 90 degrees, it is possible to ensure a sufficient friction coefficient with the clamping force between the elevator rope which is easy to slip after the oil is oozing from the inside (at this time, It is better to set the rubber hardness as low as possible, and it can control the creep sliding caused by the shear deformation when the elevator is stopped (in this case, the rubber hardness is set as high as possible), and the opposite important characteristic can be achieved. coexist. Therefore, as far as the rubber material of the belt is concerned, for example, nitrile rubber-7-(3) 1270523 glue, chloroprene rubber, polybutadiene rubber, EPDM, Η-NBR, rollable urethane (for example) Millable urethane) or a combination of these two or more. Further, in the rubber of the belt, a wire made of an aramid fiber, a nylon fiber, a polyester fiber, a glass fiber, a steel fiber, or the like, or a weaving or the like may be embedded in a loop shape. The circulation of the heart material. In addition, one or two or more types of short fibers composed of aramid fibers, nylon fibers, polyester fibers, glass fibers, and cotton fibers may be blended in the elastic material of the rubber. Short fibers can also be used on the surface. As a result, when the short fibers are fitted to the surface layer which causes the elevator rope to be subjected to friction, the abrasion resistance or the clamping force can be improved, and the shear deformation can be controlled. Therefore, the short fiber may be one or more selected from the group consisting of aromatic polyamide fibers, nylon fibers, polyester fibers, glass fibers, and cotton fibers. The rubber material of the present invention has a multilayer structure having a surface layer and an intermediate layer on the inner side thereof, and a rubber layer having the same or higher hardness as the surface layer may be formed as an intermediate layer. In this way, when the rubber material of the belt has a multi-layer structure, and the elastic material forming the intermediate layer is rubber formed by the same or higher hardness as the rubber material of the surface layer, the shear deformation can be controlled. Creep slips. As the laminated rubber material, for example, nitrile rubber, chloroprene-8-(4) 1270523 diene rubber, polybutadiene rubber, EPD Η, Η-NBR, rollable urethane or the like can be mentioned. Two or more types. It is also possible to embed one or more layers of woven fabric or/and woven fabric. When one or two or more kinds of woven fabrics or woven fabrics made of aramid fibers, nylon fibers, polyester fibers, glass fibers, and cotton fibers are embedded in the inner layer of the elastic material of the rubber, the reinforcing material is reinforced. , you can control the shear deformation. A groove portion for the shape of the elevator rope is formed on the surface layer, and a thin groove strip may be formed along the groove portion. In this way, when a groove portion such as an R-shaped groove or a V-shaped groove is formed on the surface layer of the rubber material that causes the elevator rope to be subjected to the frictional force, the shape of the elevator rope or the number (the plurality of states) may be formed. Increase the surface area in contact with the elevator rope and increase the clamping force. Further, when a groove such as a longitudinal groove, a lateral groove, or a slant groove is formed along the groove portion on the surface layer of the rubber material which causes the elevator rope to be subjected to the frictional force, the clamping can be further improved by the so-called wedging action. The force, by means of the rill strip, staggers the oil adhering to the surface of the elevator rope to maintain the clamping force. The surface layer may be covered with one or more kinds of woven fabrics and/or woven fabrics composed of aramid fibers, nylon fibers, polyester fibers, glass fibers, and cotton fibers. In such a configuration, the abrasion resistance or the clamping force can be improved when the woven or woven fabric to be impregnated or coated with the rubber or the bonding agent becomes the rubber layer of the surface. (5) 1270523 [Embodiment] [Embodiment of the Invention] As shown in Figs. 1 to 7, the elevator is connected to a case 1 (lifting case) of a passenger or an article by a lift rope 3 made of steel wire. The weight 2 (balance weight) is balanced, and the elevator rope 3 is wound around the pulley 4 at the top of the lifting path to be in a bucket type operation. Further, the pair of elevator driving belts 5 are used to sandwich the elevator rope 3 to apply the frictional force. In other words, the unilateral elevator driving belt 5 is wound between the driving pulley 7 and the driven pulley 8 coaxial with the output shaft of the winding machine 6 (motor), and the other elevator driving belt 5 is wound. Between the two driven pulleys 8, the pair of elevator driving belts 5 press the elevator rope 3 to apply a frictional force. The elevator driving belt 5 is driven by the frictional force of the cabinet 1 that connects the elevator and the elevator rope 3 of the counterweight 2, and controls the creep of the shear deformation when the elevator is stopped to make the rubber hardness set up. As shown in Fig. 2, three R-shaped (semicircular) groove portions 1 2 corresponding to the shape of the elevator rope 3 are formed on the surface layer 1 1. In the rubber of the belt, a cyclically-processed seamless aromatic polyamide wire 13 which is solvent-treated as a high-strength core material, and a three-layer polyamide woven fabric 14 are embedded. Therefore, it is possible to form a belt having high elasticity and high strength. Further, it has durability such as abrasion resistance or fracture resistance. The rubber hardness is set to about 50 to 90 degrees. In other words, the surface layer 11 is a chloroprene rubber and the hardness is set to 63 degrees, and the inner layer of the inner side -10 (6) 1270523 is a chloroprene rubber and the hardness is set to 80 degrees. Multi-layer construction. Next, the state of use of the belt for driving the elevator of this embodiment will be described. The elevator driving belt 5 is pressed against the elevator rope 3 by a pair of hydraulic devices 17, and a frictional force is applied between the elevator driving belt 5 and the elevator rope 3. Further, by adjusting the urging pressure by the pair of hydraulic devices 17, the frictional force of the belt 5 for driving the elevator toward the elevator rope 3 can be adjusted. Therefore, even if the weight reduction due to the weight reduction of the casing 1 or the counterweight 2 is caused, the frictional force received by the elevator rope 3 is reduced, and the elevator rope 3 is affected by the elevator driving belt 5. The frictional force can ensure the driving force of the elevator, and the weight of the rope 3 or the guide rail 16 supporting the elevator can be reduced, so that the overall cost of the elevator can be reduced, and the weight of the elevator can be high. It can also reduce the burden on the building. Further, since the creep of the rubber caused by the shear deformation when the elevator is stopped is controlled, the rubber hardness is set, and the stability at the time of stopping can be ensured. Since the rubber hardness is set to about 50 to 90 degrees, it is possible to ensure a sufficient friction coefficient with the clamping force between the elevator rope which is easy to slip after the oil is oozing from the inside (at this time, the rubber hardness is set as much as possible) Low is better, and it is possible to control the creep slip caused by the shear deformation when the elevator is stopped (in this case, the rubber hardness is set as high as possible), and the advantage of the opposite important characteristic can be achieved. -11 - (7) 1270523 Therefore, since the rubber material of the belt is made of a rubber material in which the intermediate layer 15 is elastic with the same or higher hardness as the surface layer 1, the creep deformation can be caused. advantage. Since the inner layer of the elastic material of the polyamide is reinforced, it is more likely that the elevator rope 3 is subjected to the frictional layer 1 1 to form the shape of the elevator rope 3 or the groove portion 1 2 , so that the elevator can be added The rope connection increases the clamping force. EXAMPLES Next, the configuration of the present invention will be more specifically described. As shown in Fig. 3, the elevator drive belt rope 3 is fixed around and is rotatably held between the fixed pulley 4 and the other pulley 18, and on the aforementioned lift 5, the load imbalance is supported by the bolt B. Hammer W. Furthermore, the belt 5-axis load F is 300 k until the unbalanced hammer W of the kgf is an unbalanced weight W that can be withstood, and it is recorded that the belt for the elevator drive is started to be slipped for being fixed to the strop 3 The load starts to slip and the load is larger, in the belt, so the rubber layer and the rope layer structure of the surface layer 1 can be judged, and the rubber material of the shape 1 is embedded in the rubber with the controlled shear deformation woven fabric. The surface area of the contact of the number of surfaces of the shear-deformed rubber material (three pieces) was controlled, and the five rolls were bent on the belt drive belt gf for raising and lowering the weight of 4 0 6 Φ, and then measured. Specifically, the smaller the deformation of the elevator rope rubber of the increase wheel 4, the smaller the slip of the cable is smaller -12- (8) 1270523 [1] As shown in Fig. 4, the elevator drive with the R-shaped groove portion 1 2 is used. The rubber hardness of the surface layer 1 1 and the intermediate layer 15 was changed by the belt 5 as follows, and then tested. (Example 1) The surface layer 11 was a polybutadiene rubber and the hardness was set to 6.3. The inner layer 15 on the inner side was also a polybutadiene rubber and the hardness was set to a degree. The result is a load of l〇4kg f. (Example 2) The surface layer 1 1 was a polybutadiene rubber and the hardness was set to 63 ° C. The inner layer 15 on the inner side was a polybutadiene rubber and the hardness was set to 80 °C. The result is a load of 12 〇 kgf. (Example 3) Diene rubber and hardness was set to 8 The surface layer 1 1 was a polytetramethylene butadiene rubber and the hardness was set to 8 Torr, and the inner layer 15 on the inner side was also a polybutylene degree. The result was a load of 98 k (Example 4). The result is a load of 8 〇 kgf. The surface layer 1 1 is a polybutadiene tantalum rubber and the hardness is set to "degree'. The inner layer 15 on the inner side is a polybutadiene rubber and the hardness is set to 6 3 degrees -13 - (9) (9) 1270523 (Example 5) The surface layer 1 1 is a polybutadiene rubber and the hardness is set to 72 ° C. The inner layer 15 on the inner side is also a polybutadiene rubber and the hardness is set. It is 7 2 degrees. The result is a load of 98 kg f. (Example 6) The surface layer 1 1 was a polybutadiene rubber and the hardness was set to 68 degrees, and the inner layer 15 on the inner side was also a polybutadiene rubber and the hardness was set to 68 degrees. The result is a load of 1 0 1 k g f. [2] The shape of the groove portion 1 2 in which the elevator rope 3 was fitted was changed as follows, and then tested. Further, as shown in the above Example 2, the surface layer 1 1 is a polybutadiene rubber and the hardness is set to 63 degrees, and the inner layer 15 on the inner side is a polybutadiene rubber and the hardness is set to 80 degrees. (Example 2) As shown in Fig. 4, the R-shaped groove portion 12 is formed on the surface layer 11 of the rubber material, but the narrow groove 19 along the groove portion 12 is not formed. As a result, the same load as described above is ]_2〇kgf. Further, the second embodiment is the same as the second embodiment of the above [1]. (Example 7) As shown in Fig. 5, along the groove portion 1 2 of the surface layer 1 1 of the rubber material, a fine groove strip 1 9 of one longitudinal groove was formed. As a result, the load is 1 3 3 kgf 〇 (10) 1270523 (Example 8) As shown in Fig. 6, the groove portion 1 2 of the surface layer 1 1 of the rubber material is made, and the narrow groove strips 2 of the 2 longitudinal grooves are made. Formed. As a result, the load was 1 8 8 k g f 0 (Example 9) As shown in Fig. 7, along the groove portion 1 2 of the surface layer 1 1 of the rubber material, the narrow groove strips 19 of the three longitudinal grooves were formed. As a result, the load is 1 7 1 kgf °. As shown in the embodiments 7 to 9, when the fine groove 1 9 of the longitudinal groove is formed, the clamping force can be further increased by the so-called wedging action, and the fineness is utilized. The groove 1 9 can be used to offset the oil adhering to the surface of the elevator rope 3. [3] As shown in Fig. 4, the elevator driving belt 5 having the R-shaped groove portion 1 is used, and the surface layer 1 is changed as follows. 1 and the rubber hardness of the intermediate layer 15 was tested. Further, short fibers are blended on the surface layer 1 1 . (Example 10) The surface layer 1 1 was a polybutadiene rubber and the hardness was set to 70 °, and the inner layer 15 on the inner side was a polybutadiene rubber and the hardness was set to 80 °C. And a cotton fiber as a short fiber is blended on the surface layer 11. The result is a load of 15 0 kg f . -15- (11) 1270523 (Example 1 1 ) The surface layer 11 is a polybutadiene rubber and the hardness is set to 80 degrees, and the inner layer 15 on the inner side is also a polybutadiene rubber. The hardness is set to 80 degrees. And an aromatic melamine fiber as a short fiber is blended on the surface layer 11. The result is a load of 300 kgf. As shown in the first embodiment, Ο, 1 1 , when the short fibers are blended on the surface layer 1 1 for subjecting the elevator rope to the frictional force, the clamping force or the abrasion resistance can be improved. Advantageous Effects of Invention The present invention is a configuration as described above, and even if the weight of the casing or the counterweight is lightened, since the driving force can be secured according to the pressing force of the belt, it is possible to provide a related product of the elevator which is highly hopeful for the weight reduction of the elevator. .
